The so-called CIP cleaning system is an in-situ cleaning system, which means that during the entire cleaning process, the on-site cleaning station equipment forms a closed loop with the production tanks, pipelines, and processing equipment, and can be cleaned without disassembling the equipment. CIP cleaning system can ensure a certain cleaning effect and improve product safety; Save operation time and improve efficiency; Save labor and ensure operational safety; Save energy such as water and steam, and reduce the amount of detergent used; Production equipment can achieve large-scale and high automation level; Extend the service life of production equipment. The detergent for CIP cleaning system can be selected based on the nature and degree of pollution of the cleaning object, the composition material, water quality, the selected cleaning method, cost, and safety. The commonly used detergents include acid, alkali detergents, and sterilizing detergents.

The advantages of acid and alkali detergents are: they can kill all microorganisms; The removal of organic matter is more effective.
Disadvantages include: strong irritation to the skin; Poor water washability.
The advantages of sterilizing agents include: rapid sterilization effect, effective on all microorganisms; Diluted is generally non-toxic; Not affected by water hardness; Form a thin film on the surface of the equipment; Easy to measure concentration; Easy to measure; Can remove odors.

Disadvantages include: having a special taste; Requires certain storage conditions; The sterilization effect varies greatly among different concentrations; Easy to freeze when the temperature is low; Improper use can lead to side effects; The sterilization effect significantly decreases when mixed with pollutants; When scattered, it is easy to contaminate the environment and leave traces.

The acid in acid-base detergents refers to a 1% -2% nitric acid solution, while the alkali refers to a 1% -3% sodium hydroxide solution used at 65 ℃ -80 ℃. Sterilizing agents are commonly used chlorine based disinfectants, such as sodium hypochlorite.

The influencing factors of cleaning effect include the degree of equipment pollution, the nature of pollutants, and the production process of the product. It is an important reason for determining the cleaning effect. If the CIP conditions are not determined based on their characteristics during cleaning, it is difficult to achieve the ideal goal or lead to defects such as high cleaning costs. There are many types of cleaning agents currently used in the food industry, mainly including acids and bases, among which sodium hydroxide and nitric acid are the most widely used. Alkaline detergents have a good removal effect on pollutants with high protein content, but they have a certain corrosive effect on food rubber gaskets, etc. Acid based detergents have a good effect on stubborn dirt that alkaline cleaning agents cannot remove, but they have a certain corrosiveness to metals. Therefore, some anti-corrosion agents should be added or rinsed clean with water. Cleaning agents also include surfactants, chelating agents, etc., but they should only be used when necessary. For example, chelating agents can be used to remove metal ions when the hardness of the cleaning water is high. When the concentration of the cleaning agent is increased, the cleaning time can be appropriately shortened or the insufficient cleaning temperature can be compensated for. An increase in the concentration of cleaning agents will result in an increase in cleaning costs, and an increase in concentration may not necessarily effectively improve the cleaning effect. Therefore, it is necessary for manufacturers to determine the appropriate concentration based on the actual situation. Generally speaking, for every 10 ℃ increase in temperature, the chemical reaction rate will increase by 1.5-2.0 times, and the cleaning speed will also increase accordingly, resulting in a better cleaning effect. The cleaning temperature is generally not lower than 60 ℃. The cleaning time is influenced by many factors, such as the type and concentration of cleaning agent, cleaning temperature, product characteristics, production pipeline layout, and equipment design. The cleaning time must be appropriate, too short cannot effectively remove dirt, and too long will waste resources.

CIP cleaning system program
Taking the beverage industry as an example, its cleaning procedures are as follows:
Wash for 3-5 minutes with hot water at room temperature or above 60 ℃; Alkaline washing for 10-20 minutes, 1% -2% solution, 60 ℃ -80 ℃; Wash for 5-10 minutes in the middle with clean water below 60 ℃; Finally, wash for 3-5 minutes with clean water.
Wash for 3-5 minutes with hot water at room temperature or above 60 ℃; Alkali wash for 5-10 minutes, 1% -2% solution, 60 ℃ -80 ℃, intermediate wash for 5-10 minutes, clear water below 60 ℃, sterilize for 10-20 minutes, hot water above 90 ℃.
The guarantee of cleaning flow rate is actually to ensure the flow rate of the cleaning solution during cleaning, thereby generating a certain mechanical effect, that is, by increasing the turbulence of the fluid to enhance the impact force and achieve a certain cleaning effect.
